I ROLLER SHADE ATTACHMENT I Filed Oct. 12, 1934 INVENTOR ATTORNEYPatented Dec. 3, 1935 UNITED STATES PATENT OFFICE 1 Claim.

The invention relates to a roller shade attachment and more especiallyto a shade stop.

The primary object of the invention is the provision of an attachment ofthis character, wherein the same is carried at the free end of a rollershade so that when the latter is wound upon its roller the shade will beprevented from overwinding and thus such shade will be assured of smoothand tight winding upon the roller.

Another object of the invention is the provision of an attachment ofthis character, wherein should it happen that a shade is snappedsuddenly by the spring tensioned roller carrying the same, the saidshade will be arrested and thus avoid the unwinding of the spring withinthe roller and at the same will limit the winding action of the shadeupon the roller, the attachment being ornamental in effect.

A further object of the invention is the provision of an attachment ofthis character which is simple in construction, thoroughly reliable andefficient in its purpose, readily and easily applied to a window shade,neat and attractive in appearance, durable, and inexpensive tomanufacture and install.

With these and other objects in view, the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described in detail, illustrated in theaccompanying drawing, which discloses the preferred embodiment of theinvention, and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure 1 is an elevation of a shade, showing the attachment constructedin accordance with the invention applied thereto.

Figure 2 is an edge elevation.

Figure 3 is a plan view of one part of the attachment in blankformation.

Figure 4 is a view similar to Figure 3, showing a slight modification.

Figure 5 is a fragmentary edge elevation.

Figure 6 is a fragmentary plan view of a further modified form.

Figure '7 is an edge view thereof.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawing.

Referring to the drawing in detail, A designates generally a rollershade for a window or the like which is of conventional kind adapted tobe wound on and unwound from a spring tensioned roller B of well knownconstruction, the

said roller being mounted at each end in a bracket 10 for the placementof the shade in position with respect to a window or the like. The shadeA, at its free end, is provided with a casement H in which is fitted theshade stick I2 and at this end 5 of the shade A is applied theattachment constituting the present invention and hereinafter fullydescribed.

The attachment comprises a pair of angle pieces l3, each formed frommetal and cut and 10 shaped to present a pleasing design, as at l4. Eachpiece l3 has the bendable tongue l5 which is turned about the casementll carrying the stick l2 at one corner of the shade A to lie at theinner side of such shade and the tongue I 5 being 16 of a widthcorresponding substantially to the width of the casement ll, whilepassed through the said tongue and the component part of the piece I3 isa fastener [6 for the securing of such piece in place, as shown inFigure 1 of the draw- 20 ing. It is, of course, understood that the pairof pieces [3 are worn by the shade at the corners of the free endthereof, this being apparent from Figure 1 of the drawing.

In Figures 4 and 5 of the drawing there is 25 shown a slightmodification, wherein the tongue I? is formed at one end edge of thepiece l8, while in Figures 6 and '7 there is shown a still furthermodification, wherein the piece H! has struck therefrom bendable spursor teeth 20, 30 which bite into the shade A and the stick l2 as confinedwithin the casement II, and in this manner the piece I9 is made firm andsecure to the shade.

It will be apparent that when the shade A is 35 wound upon the roller Bthe pieces l3, l8 or [9 will abut the head of the window, as at 2| inFigure 2 of the drawing, to avoid the overwinding of the shade upon theroller and also to effect the tight and smooth winding of the shade upon40 said roller.

What is claimed is:

In a window shade attachment a body piece for fastening to a windowshade and having a portion which runs off at substantially a tangent 45to the roll of fabric of the shade at the point where its attachment tothe shade contacts that portion of the shade which is already wound on aroller and such portion being of a length enough in the direction ofmovement of the shade 5 to contact with a window casing at its top forlimiting the winding of the shade upon the roller.
